Black Holes Slamming into Wolf-Rayet Stars May Explain the Universe's Most Mysterious Blue Flashes
Summary: Astronomers have proposed a new theory: Luminous Fast Blue Optical Transients (LFBOTs) — the universe's brightest and fastest blue optical explosions — may be caused by compact objects like black holes or neutron stars slamming into the universe's hottest class of stars, Wolf-Rayet stars, rather than conventional supernova or tidal disruption mechanisms.
